A sport-wheeled chassis is provided for connecting to a mobility device, which comprises a suspension set up under the bottom of the mobility device, a steering pivotally connected to the suspension, a controller connected to the suspension and steering electrically, tires which are pivotally connected to the steering and disposed under the steering, and a steering shaft of the steering which coincides axially with the steering shaft of the tire so that the controller can operate the turning direction of the tire and the height of the suspension through the suspension and the steering. The chassis is not only with a simple structure, but also with a suspension to control the height of the chassis off the ground, so that the chassis can maintain stability in any rugged environment, and, with its attached wheels, the chassis can move to desired places fast and accurately.

A method for managing a traffic situation associated with a road user and a turning combination vehicle. The combination vehicle comprises a first vehicle unit and a second vehicle unit. The method comprises obtaining sensor data indicative of traffic information from respective sides of the vehicle units from a set of sensors. The traffic information is indicative of respective turning motions of the vehicle units, and a position of the road user. The method further comprises determining respective trajectories of the vehicle units based on the respective turning motions of the vehicle units. The method further comprises establishing a region of interest extending along the determined trajectories. The method further comprises determining whether the position of the road user is within the established region of interest. The method further comprises, when the position of the road user is determined to be within the established region of interest, triggering preventive action.

A method includes ascertaining a first drive force and a second drive force for a first drive axle and a second drive axle of a vehicle, ascertaining a first slip value and a second slip value for the first drive axle and the second drive axle of the vehicle, determining a first slip measured value for the first drive axle from the first drive force and the first slip value and determining a second slip measured value for the second drive axle from the second drive force and the second slip value, determining a total torque that is to act altogether on the first drive axle and the second drive axle, and dividing the total torque into a first desired torque and a second desired torque in dependence upon the first slip measured value and the second slip measured value.

A method for controlling a vehicle combination includes receiving a request that a desired force imparted on the vehicle combination should be provided by the set of motion support devices of a unique dedicated unit of the vehicle combination, the unique dedicated unit being either the tractor or the trailer. Upon determining that the desired force imparted on the vehicle combination can be provided by the set of motion support devices of the unique dedicated unit whilst fulfilling each safety requirement in a predetermined set of safety requirements of the vehicle combination, the predetermined set of safety requirements includes at least one safety requirement, operating the set of motion support devices of the unique dedicated unit only so as to provide the desired force, otherwise operating one or more of the tractor motion support devices as well as one or more of the trailer motion support devices in order to provide the desired force imparted on the vehicle combination.

A transport power system is provided. The system includes a prime mover separate from a vehicle engine; a global positioning system (GPS) receiver configured to receive GPS data; and a controller configured to communicate with the prime mover and the GPS receiver. The controller is configured to determine an altitude of the transport power system with respect to sea level based on the GPS data received by the GPS receiver, determine a power output of the prime mover, adjust a power output upper limit for the prime mover based on the determined altitude, compare the power output of the prime mover and the adjusted power output upper limit, and operate the prime mover of the transport power system so as not to exceed the adjusted power output upper limit.
